Volkswagen 4industrial engine Technical DataAFD 02.97


Manufacturers declaration in accordance with Article 4, Paragraph 2 inconjunction with Appendix II, Section B of Directive 89/392/EEC in the version93/44/EEC

Note

The engine described is intended for installation in a machine in the sense of the ECMachines Guidelines. It is not permitted to take this engine into operation until it hasbeen demonstrated that the machine into which this engine is to be installedcomplies with the stipulations of the EC Machines Guidelines (89/392/EEC, lastamended by 93/44/EEC).

Introduction

The Volkswagen industrial engine with the engine code AFD is a 1.9-litre water-cooled 4-cylinder in-line diesel engine with direct injection, exhaust gas turbochargerand intercooler. With the numerous different areas of application for this engine, thenotes on the following pages should be studied carefully prior to the development ofnew machines. This is to ensure problem-free operation and a long service life forthe entire machine, under all operating conditions.

Design: Direct valve control via toothed-belt-driven overhead camshaft (ohc).Maintenance-free valve drive via hydraulic tappets. Distributor-injectionpump electronically governed by control unit and driven by toothed belt.
